2014 Denali. Mods in Signature. All Components in excellent shape.
On occasion after a longish drive. After Turn engine off. Wait a bit, like filling gas.
It won't start/crank. I've even put a jump box on it with no crank.
Tested Alternator (less than 6 mo old -GM unit) Tested Battery - always test excellent (less than 6 mo old)
Both positive and negative cable assemblies are less than 3 years old. Starter is actual GM starter about 3 yrs old
When this happened I had been towing for about 75 miles. All gauges and parameters were great. I'm
OCD about monitoring everything esp when towing. Ambient temp was a cool day about 80* out.
When I turn on key everything lights up normal, then when crank it's NOTHING... No click ,,, nothing.
After I jacked with it and even trying jump box starting it, nothing....
Then after about 15 minutes it cranked and ran absolutely normal.
Looking for Ideas of a possible electrical issue. Maybe an ignition switch ?? IDK
I have been paranoid to drive it anywhere since this happened, but If I run out to the driveway at any
time it will crank right up and start/run normally.
I did a battery crank test, alternator test , and a starting time test: all normal/good
